Planetary Gear Testrig
This example models a planetary gear with three planets. The planetary gear has three mechanical connections: sun gear, carrier, and ring gear. Driving and locking different pairs of shafts will produce different movements.

Model

Planetary Gear Subsystem
This subsystem shows the parts, joints, and gear constraints used to model the planetary gear.

Carrier Gear Subsystem
This subsystem shows the used to model the carrier, which connects the planets.

Sun Shaft Input Subsystem
This subsystem models the input to each shaft. Signals control the torque applied to the shaft and the enabling of a brake.

Simulation Results from Simscape Logging
The plot below shows the speeds of the three shafts attached to the planetary gear as different pairs of shafts are driven and locked.
